Who gets to define n?

I don't know actual statistics, but I think that in every place there is something like a "normal temperature" each season.

Whoever has the most firepower.

[wunderfool]

no one. we do not have the technology to rapidly alter the climate. our current climate change is the result of thousands of years of population growth and industrialization. concepts for extracting CO2 from the atmosphere in short course are just that, concepts

mother nature is still in charge, and needs only shrug slightly with a temperature change of 10 degrees on average in either direction to eliminate humans and our society

[jarin]

Somehow I doubt a 10 degree shift (F) would eliminate humans altogether, since humans have likely gone through a population bottleneck of 1,000-10,000 breeding pairs: http://en.wikipedia.org/wiki/Toba_catastrophe_theory
